With direct shift transmission, the gearshift forks are operated hydraulically and not by gear linkage as with conventional transmissions. The gearshift forks are mounted with ball bearings in a cylinder. For gear shifting, the mechatronic system forces oil into the left or right cylinder. This possibility is shown on the right-hand side of the model. The hydraulic piston is positioned directly on the shifter rail. On the left, an extra shift cylinder with gear changing piston has been installed, which is connected to the gearshift fork and takes this along for gear changing.
